Asthma: Pathogenesis and Management01:20

Asthma: Pathogenesis and Management

1.7K
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

2.4K
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

4.0K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

Asthma-II: Pathophysiology and Classification

4.9K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Glaucoma: Overview01:25

Glaucoma: Overview

1.7K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Background:

  • The exact causes of cluster headache remain unclear.
  • Cluster headache pathogenesis involves trigeminal nociceptive pathways, the autonomic system, and the hypothalamus.
  • Cluster headache attacks are characterized by the activation of the trigeminal autonomic reflex.

Purpose of the Study:

  • To explore the multifactorial etiology of cluster headache.
  • To investigate the role of the hypothalamus in cluster headache pathophysiology.
  • To identify potential contributing factors such as smoke exposure and genetic predisposition.

Main Methods:

  • Review of existing literature on cluster headache.
  • Analysis of neurobiological pathways involved in cluster headache.
  • Correlation analysis of environmental and genetic factors.

Main Results:

  • Posterior hypothalamic gray matter dysfunction is likely pivotal in cluster headache.
